1 Claim. 1

This invention relates to apparatifiior washing milking machines, as commonly employed in dairies. and the principal object of the invention is to provide a relatively simple. compact and eflicient apparatus for this purpose, embodying few parts and which therefore may be constructed at a relatively low cost.-

Another object of the invention is to provide in an apparatus of the kind referred to. a suitable supporting frame having a washing tub or basin mounted at one side of the upper portion of the frame. a water and pressure tank in the opposite side of the frame. a valve-controlled drain pipe leading from the bottom of the washing tub into the said water and pressure tank, a valve-controlled air pressure pipe leading from the top of the water and pressure tank and directed over,

the washing tub, a water'pipe leading from the bottom of the water and pressure tank and directed over the washing tub adjacent and in parallel relation to the air pressure pipe, the said water pipe being also valve-controlled, a common delivery nozzle connected to the adJacent free ends of the air pressure pipe and the water pipe. and a pressure gauge on the air pressure pipe for indicating the air pressure within the said water and air pressure tank.

With the foregoing objects in view, together with such other and additional objects and advantages as may appear from the specification, attention is directed to the accompanying drawing as embodying and illustrating a preferred construction of the invention, and wherein;

Figure 1 is a side elevation of the apparatus,

Figure 2 is an end elevation,

Figure 3 is a top plan view, and

Figure 4 is a fragmentary detail view on an' enlarged scale and in longitudinal section along the line A-A of Figure 3. of the delivery ends of the air pressure and water pipes, at their juncture with the delivery nozzle.

The invention comprises a suitable supportin; frame such as represented generally at i,

and which includes the corner posts Ia and the cross bars lb. This frame is oblong on a top plan view, as shown in Figure 3, and a washing tub or basin 2 is mounted by its upper margins within one end of the frame in the upp r side thereof, being suspended as shown from the upper bars lb of the frame. An elongated cylindrical tank 3 is mounted vertically in the opposite end of the frame, being supported upon short legs Ia.

A drain pipe it connects the bottom of the tub 2 with the top of the tank 3, through the side 2 of a connecting collar la located at the top of the tank and this pipe 4 is controlled by the screw valve H for permitting the washing solution to flow from the tub 2 down into the tank 3. as may be desired in the operation of the apparatus.

A feed pipe 5 is connected at 317 to the bottom of the tank 3. and is thence extended upwardly along the tank to a point substantially above the tub 2, and a horizontal extension to, by means of the outer angular nipple 5b, is extended over the tub 2 and at the rear side thereof as shown in Figures 1. 2 and 3. A delivery nozzle 9 is connected to the end of the pipe over the tub 2. through the inner angular nipple 5b. this said nozzle being directed vertically downward towards the tub. as shown. A compressedair pipe 6 is extended vertically in parallelism with the pipe. 5. and by means of the horizontal extension 6a and the T-nipple 6b is connected through the upper end oi the collar la with the tank 3. A screw valve iii controls the flow of compressed air into and through these pipes, as same may be delivered from a compressor or any conventional source into the pipe. Another horizontal extension 60, in parallelism with the extension 5a of the pipe 5, extends inwardly over the tub 2. and by means of the outer angular nipple 6d and the inner T-nipple Se is connected with the said' delivery nozzle 9. A pressure gauge 8 is provided and is mounted upon the compressed air pipe 6 by means of the branch pipe 80, in a conventional manner. Another screw va-lve i2 is mounted on the pipe 6, above the gauge 8, and a similar valve I3 is mounted on the pipe 5 in transverse alignment with the valve l2, for controlling the ilow of the cleansing solution through the feed pipe 5.

In the operation of the described apparatus for washing and cleansing milking machines, the valves III, II and I2 are closed and the valve i3 is left open. The washing or cleansing solution (not shown) is then poured into the basin or tub 2, and the hose of the unit to be washed is attached to the end of the nozzle 9. The valve H is then opened to permit the solution to run from the tub 2 down into the tank 3. Valves H and I3 are then closed and valve I0 is opened into and through the milking unit. with the solution thus flowing valve I2 is opened for permitting compressed air to flow through the pipe t and nozzle 9 along with the solution already flowing. The air pressure breaks up the stream of washing solution into pulsating jets, which quickly cut all impurities from the interior surfaces of the milking unit. If thought necessary, the inner sides or surfaces of the teat cups may be brushed out with a power or hand operated brush. To complete the operation close valves l2 and I3 and remove the cleansed unit. While I have here shown and described a preferred embodiment of the invention, and certain specific structural features thereof, it is understood that various changes and modifications may be made in the structures as shown, within the scope of the claim.

I claim: 7

An a paratus for washing milking machine and the like comprising a supporting frame, a basin supported by the frame. a water-and-airpressure tank located below the top of the frame, a drain pipe connecting the bottom of the basin with the top of the tank, a valve in the drain pipe for opening and closing communication between the basin and the tank, a water pipe extending the frame.
